SoftXMLLib 3

By Movsesyan Gregory on Jan 3, 2007

General

One of the main problems with manipulating XML files is the compatibility issue across different browsers. The purpose of the SoftXMLLib Library is to solve the problem of creating different XMLHTTP and XMLDOM objects for different browsers. This library includes basic functions and properties like those already included in Microsoft.XMLDOM ActiveXObject.
